PATRICK BURNS and JOHN RnARDoN, `both,

citizens of` the United States, andy residents of Fort Edward, in the county of Washington and State of yNew York, have made certain new and useful Improvementslin Flue-` Blowers, of which the following is a specifi-i cation. y Y j j Our invention is an improvement in flue blowers, and has for itsobject kto provide a device of the character speciiied for use in connection with furnaces of any character, for blowing out boilers, whereinthe' blower is so arranged that it may be-usedfrom the rear to blow in conjunction with the draft,

to thus eliminate the reta-rding effect of the draft, and wherein the blower is so arranged that it will be protected from the heat of the furnace when not in use. j

In the drawings: Figure lis a transverse vertical section, Fig. 2 is a section on the line 2-2 of Fig. 1 looking inthe direction of the arrows adjacent to the line, and, Fig.`

3 is a sectionon the line 3 3 of Fig. `2 looking in the direction of the arrows adjacent to the line. y

The present embodiment ofthe invention is shown in connection with a boilerl of ordinary construction, mounted in a casing2 of brick, which supports the boiler, and pro vides a furnace for heating the same. Thez boiler has the usual draft tubes 3 extending longitudinally thereof.

It will be understood that in order to blow out a boiler from the front end, a considerf able length of time will be required, and'y since the blowing is in opposition to the normal draft, this draft will be interrupted during the blowing out of the boiler. Frein 1-5 to20minutes is required to blow outfthe boiler in the usual arrangement, and hence no steam is made until the operation isfinfy islied. Because of the blowing being in opposition to the `normal draft, the soot blown from` one tube rfwillfbe carried back toward the front and will settle in the tubes which have been already blown. Because of "this difliculty,.the present blower is arranged to blow out the flues from ther rear of the boiler, and because of the intense heat at this point, there must be some ,protection for the blower when not `in use, in order that the-pipes and the fitting may not become -UN1TEB STATES-PATENT y injured Yor destroyed by the excessive heat. e

. Thepresent construction is `arranged to blow out the boiler fromthe rear, butmeans is` provided for protecting the blow out mechanism from the excessive heat.

They invention comprises a pipe 5 having cov one end closed by a cap G threaded on to the i pipe, and the pipe is provided with a series of nipples 6 extending laterally from the" pipe, the members of the 'series extending' longitudinally of the pipe. The pipe is con-. nected at its upper end by means of an elbow 7` with' another section 8 of pipe', which isarV ranged within a tubular casing 9 mounted in the wall of the casing 2, `and extendingA outside of the same, at the rear of the casing, as shown iny Fig. 2. The pipe 5 is the blow pipe, and thegnipples 6 are designed to register with the tubes 3 of the boiler.r4 The pipe 8 is mounted toy rotate in the tubular casing'and the inner end of the said pipe extends intoa casing l() whichy is mounted in a recess1 aty one sidcvof the furnace open,e ing. This casing isfrectangular in cross section, being of a length sufficient to receive the, pipev 5, yand being of a cross Asection to provide ample roomin the pipe, when Vin the casing. The pipe normally hangs verticallyfin the casing, as shownin Fig. l', out of contact withy the walls of the casing, so that it lwillreceive no heat directly from the` casing 2 of the furnace, or from .the casing l0 for ythe pipe'. This casing l0 is arranged at the rear of the boiler,.as before stated i and at one side of they furnace opening, and

the casing is provided with a door opening.

At the side adjacent tothe boiler, the said opening registers with anzopening ll in the casing wall 2 of the furnace. It will be noted from an inspection of Fig. 3 'that-the casing '10 is set with-in the inclosing wall 2, and that there is a portionkk of the inclosing wall between the casing 10 andv the interior of the furnace,fandthat the opening 1l regj isters'with the door opening of thecasing. The door opening and the opening ll are of suchlength, and so arranged with respect to the pipe y5, that the said pipe will swing out through the door opening and throughf the opening 11 when thel pipe 8 is rotatedy in the tubular casing 9. z j Adoor 12 is providedy for closingthedoor opening, the said door being.' hinged to the i casing one side thereon-andbeing mounted to swing ,intol the casing, asindicated in dotted lines in FigB. A handle A is connected with the door, the said handle extending upwardly from the'top'of the cas- Y ing Wall 2 and outside ofy the said wall,"and the handle is Vprovided with an angular portion 14 at its upper end for convenience 1n swinging the door. The door 1s hinged or pivoted on the handlerl?) and on a dowel pin `15i`n suchl mannerV that when the handle 13 is oscillated byfmeans of the angular portion 14 the door will be swung inwardly into the casing 10.5 The `door is provided lon its outer face with a longitudinally extending 'recess v16,-having its'side walls and itsV bottom wall -,undercut,' as Vsh-own in Figs. 1 and 3, and a facing 17 of fire'brick or'the like Vis arranged in the recess. VVihenthe door is closed, theV interior ofthe casing-10 is shut off from the heatof thel furnace,` and thefacing17 .of insulating material is of sufficient width to y extend entirely across the-opening 11,;so that v none ofthe wall of the casing 10'nor of the door 12 is subjected to the directaction of the heat from the furnace. Y

The pipe 8 is oscillated' by' means of a handle 18, the said handle being connected YtoA the pipe outside of the casing 2. This handle is-provided with a head 19 Vfitting over the pipe, on one side` of acollar 2O that encircles the pipe, and thepla'te 21 is provided with a' central opening forreceiving the pipe, andfits-over the pipe outside of the collar. The head 19 is provided with threaded stems 22 ,-which pass through openings in' the ends of the plate, and nuts 23 are threaded on tothe stemsv for clampingv the plate',

and the head on the collar. yIt will be understood that the outer end of the pipe '8 isV connected withthe blowing mechanism.

In-operation, when it is desired to blow J out the tubes of the boiler, the 'handle 14 is handle 13 and on the'ydowel pin 15.

grasped and ,moved in a direction to oscillate the handle 13,- to swing the doory on the cally of the boiler in order that a number of tubes may be blownr at the same time. lSince,

the mechanism is arranged inrear of the boiler, the direction in whichthe draft tubes are blown is in thesame 'direction as the-V draft,so that the heat-of the boiler is not reducedin anyway during the blowing.

They boiler is 1 also provided with a downblowout pipek consistingof a vertical portion 24 .and a vhorizontal portion .24?. f The verti- The cal portion 24 extendsdownwardly from the; Y

boiler inthe furnace and the horizontal porc tion 24i extends'rearwardly outsidegof'the casing 2. 1
